On the Fact that the U.S. Condemned the Japanese Invasion of Manchuria to the Tune of Harsh Economic Sanctions While at the Same Time Totally Ignoring the Soviet Occupation of Mongolia Which Included Joseph Stalin Completely Liquidating that Country's Buddhist Institutions

Yeah, it seems that only fascist aggression bothered FDR as he was apparently willing to let Joe Stalin get away with just about anything (including invading Poland - the country that we were supposed to be liberating!!!!!).
